Yes it's high profile 40mbps 1080p. But then again, if you want to play files from a box and all you do is play baseline blurays, then I don't see the point. I believe such a box should play "anything" HD.
The page also report their own tests http://www.auby.no/files/video_tests/ http://www.auby.no/files/video_tests/
Bird certainly lags to death on my exynos 4210
- DannyBee 14y agoThe hardware decode blocks in each processor/GPU/etc are rated to handle certain bitrates at certain profiles. The tech sheets usually specify. Going over those bitrates is usually death on these types of CPU's. They don't put much work into software decode, and even if they did, it wouldn't even come close. A lot of the cheaper ARM SOC's folks are talking about have decode blocks (either in CPU or GPU) that can only do H.264 high profile @20mbps or 30mbps at best. By comparison, intel hd graphics (even the oldest ones) will support decode of at least 40mbps of high profile h.264 (and newer ones often have no problem with 100mbps). Nvidia's purevideo hd and ATI's UVD can do the same, obviously. Realistically, if you want a box that plays stuff out of the mainstream (and honestly, mainstream is 20-30mbps or less right now) you have to pay more for it.
